AlQa'dah 1, 1436, Aug 16, 2015, SPA -- Authorities pulled more bodies from a massive blast site at China's Tianjin port, pushing the death toll to 112 on Sunday as teams rushed to clear dangerous chemicals and prosecutors prepared an investigation into those responsible for the disaster. More than 700 people were injured and 95 people, including dozens of firefighters, are missing after a fire and rapid succession of blasts late Wednesday hit a warehouse for hazardous chemicals in a mostly industrial area of Tianjin, 120 kilometers (75 miles) east of Beijing, AP reported. By Sunday, authorities confirmed there were "several hundred" tons of the toxic chemical sodium cyanide on the site at the time of the blasts, although they said there have not been any substantial leaks. Sodium cyanide is a toxic chemical that can form a flammable gas upon contact with water, and several hundred tons would be a clear violation of rules cited by state media that the warehouse could store no more than 10 tons at a time. Tianjin officials have ordered a citywide check on any potential safety risks and violation of fire rules, mandating suspension of operations for factories that cannot immediately comply with safety rules. Chinese Premier Li Keqiang was in Tianjin on Sunday, visiting those injured and displaced by the disaster.
